SPECIFICATION forming part of Letters Patent No. 401,817, dated April23, 1889.

Application filed January 15, 1885- .Serial No. 152,995. (No model.) I

To all whom it III/(by concern.-

Be it known that I, PHILIPP CHARLES GLosE, a citizen of the UnitedStates, residing at Augusta, in the county of Richmond and State ofGeorgia, have invented certain new and useful Improvements inHarvesters, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to mowers; and it consists in certainimprovements in the construction of the same, as hereinafter described,and specifically set forth in the claims.

In the accompanying drawings like letters represent like parts in allthe figures.

Figure 1 is a side elevation of a mower provided with my improvements.Fig. 2 is a plan view of the same. Fig. 3 represents in perspective thethree parts forming the connection between the connecting-rod and thecutter-bar. Fig. at is an elevation of the driving-wheel and of thedevices operating the cutter-bar. Fig. 5 is avertical sectional view ofthe hollow connecting-rod and its coupling with the cutter-bar. Fig. 6is a plan of the cutter-bar and spring thereof. Fig. 7 is aside view ofa portion of the harvester, showing the supporting-wheel attached to theinner shoe and its operating-lever. Fig. 8 is an enlarged side view ofthe wheel attached to the shoe. Fig. 9 is a vertical section of thesame.

In the drawings, A represents the drivingwheel provided withcorrugations A, located on the outer side thereof. These corrugations Aare to give a rocking motion to the driving-beam B by means offriction-rollers B at the ends thereof, and said beam gives anoscillating motion to the connecting-rod B, and the latter gives areciprocating motion to the cutter-bar B The driving or rocking beam Bcarries-a friction-roller, B, at each end, which are set at such anangle relatively to the pivot B as to cause the small friction-rollersB. to travel upon the corrugations and follow them closely to pro duce aregular, uniform, and positive stroke of the cutter-bar B The lower endof the beam B, or of its connecting-rod B rigidly secured thereto, ismade hollow to receive the stem B of the hollow cylindrical socket B andwithin the latter is located the horizontal cylindrical pin B that isprovided with a socket to receive the vertical pin 1), projecting upwardfrom one end of the cutter-bar B and thus a reciprocating motion isimparted directly to the latter. The pivot B of the beamB passes throughan eccentric, 0, located about midway between the two friction-r0llersB. This eccentric is inclosed in a band, carried by and forming part ofthe frame 0 that is connected With the shoe supporting the finger-bar.This frame stands across the face of the driving-wheel, and the rollersB are therethrough kept to their places opposite the corrugations andpermit therollers B to be thrown in and out of gear with thecorrugations A.

The eccentric C is actuated by means of a hand-lever, 0 having itsfulcrum in a bearing fastened to the thill a and located on the innerside of the driving-wheel A. The beam B and frame C carrying thefricton-rollers,l

are connected with the main axle by crossbraces consisting of two arms,D and D, located one 011 each side of the driving-wheel A, and made toencircle the main axle of the machine. The friction-rollers B are madeof rawhide or covered with rubber, to render them elastic and noiseless,and are provided with shields h of any suitable material.

The finger-bar F is connected to the axle by means of braces I, and canbe elevated by the chain d and bell-crank lever d. The beam B and itsadjuncts are retained in proper position relatively to the cutter-barand its shoe by the brace e, and to the latter is secured the bentspring E, the ends of which bear against shoulders f upon the cutter-barB on each side of the connecting-rod B, that moves the cutter-bar toprevent the wear and tear of beam B and parts attached thereto.

The small wheels G, located at each end of the finger-bar, have tires Gprovided on. their outer edge with a circular cutter or colters, G,integral therewith, to cut and divide the weeds, grass, &c., in thepath, and prevent the choking of the cutter -bar. The small wheel G,nearest the driving-wheel A, is pro vided with a central disk, G whichturns loosely therein, and this disk is provided with a stud-pin, g,eccentrically projecting from the inner side thereof, to which isattached a shoe which supports the finger-bar F From the outer side ofthe disk Gr eccentric ally projects an arm, g, to the outer end of whichis attached the lever H. This lever extends from the arm 9 to withineasy reach of the driver, and is provided with a rack, H, on the underside thereof, the teeth of which are made to engage a pin, H attached tothe main frame or to one of the thills a. The arm g, actuated by thelever H, rocks the eccentric G and thus, through stud-pin g, raises andlowers the finger-bar F without changing its parallelism to the ground.

The above-described improvements and at tachments of new machinery canbe applied to mowers, reapers, and binder machines.

The beam B has a bend in the middle of its length at the pivot 13*, sothat the force against the corrugated track is substantially at rightangle to the arm B at the points where the rollers bear against saidtrack, and so that the friction-rollers B at each end are supported by astraight arm from the pivot B to the bearing-points of said rollers, andsaid arms are substantially parallel with the working-planes on thesurface of the corrugations and enable the small friction-rollers at theends to pursue at all times while running an even smooth course up anddown the corrugations, and this is one of the features of this device.The pressure-rollers C protect the main wheel against uneven lateral orside pressure from the rollers B, and these rollers, being set in frameC form altogether compact means for the raising and lowering of thefinger-bar F, with all the balance of my machinery attachment, by thedriver merely pulling on handle (1, even while the machine is inoperation.

The driving friction-rollers B, that run in the corrugations, are madeof iron covered with rawhide or india-rubber, which makes an elasticcushion, which prevents wear of the corrugations and renders theoperation of the machine noiseless.

Having now fully described my invention, I claim 1. In combination withthe driving-wheel A, having corrugations upon one side, and the beam B,provided with rollers bearing thereon, the tubular connecting-rod Bintegral with said beam and having inserted into its lower end avertical pin, B having a cylindrical socket, B, a horizontal cylindricalpin inclosed in said socket, and a pin projecting upward from thecutter-bar and entering a socket in said cylindrical pin, substantiallyas and for the purpose described.

2. In a harvester, the oscillating beam B and connecting-rod B rigidlyattached thereto and having its lower ends provided with a tubularsleeve, the stem B therein carrying the horizontal cylindrical socket Band the cylindrical pin B within the latter, in combination with a pin,1), entering a socket in said pin B and secured to the cutter-bar Bsubstantially as and for the purpose described.

3. In a harvester, the oscillating beam B and pivot B thereon, theeccentric 0 upon said pivot in front of said beam and provided with ahandle, the band C upon said eccentric, and the frame C to which saidband is attached, the brace e, and the bent spring E, having its middleportion secured to the lower end of said brace, in combination with thecylindrical socket B having the stem B within the socketed rod B of thebeam B, the horizontal pin B within the socket B and the vertical pin1), received into the pin B and projecting from the cutter-bar,substantially as described.

4. In combination with the finger-bar, a raising and lowering devicetherefor, consisting of a disk, G within the wheel G, a studpin, g, onthe inner side of said disk carrying the shoe and cutter-barattachments, and the arm g, located on the outer side of the disk, alever, H, provided with a rack, and a pin, H attached to the main frame,substantially as and for the purpose described.

In testimony whereof I affiX my signature in presence of two witnesses.

PHILIPP CHARLES CLOSE.
